Plant root species form 3-D image reconstruction system and method

Abstract

The invention discloses a three-dimensional image reconstruction method for the patterns of plant roots, which includes the following steps: shooting photos around the detected plant roots from each scheduled point of view; processing the photos to obtain the two-dimensional coordinates information of the pixel points which represents the plant roots in the photos, obtains the three-dimensional coordinates of all points corresponding to the pixel points which represents the plant roots on each shot photo according to the corresponding relation between the three-dimensional coordinate of a physical space and the two-dimensional coordinate of each image projection plane of the physical space; selects certain specific three-dimensional coordinates as the scene point coordinates of a three-dimensional image space and forms a three-dimensional image with binaryzation through the scene point coordinates. The invention also discloses a three-dimensional image reconstruction system for the patterns of plant roots. The invention has the advantages of high speed, high accuracy, etc., and can be used indoors and outdoors.

Description

technical field [0001] The present invention relates to three-dimensional image reconstruction, in particular to a three-dimensional morphological image system and method of plant roots. Background technique [0002] Quantitative description and analysis of the three-dimensional architecture of plant roots is one of the important means to study plant root growth and nutrient functions such as nutrient uptake and utilization. [0003] The root system is not only the main organ for plants to absorb nutrients and water, but also plays an important role in supporting the shoot. Plant root architecture refers to the spatial distribution of roots in the growth medium. Different root architectures significantly affect important physiological functions such as nutrient and water absorption and utilization, carbon source distribution, and ability to adapt to environmental stress, and even affect the root system of some legumes. In recent years, more and more attention has been paid ...

Problems solved by technology

Some people quantitatively study the two-dimensional root structure of plants through special cultivation systems such as paper cultivation combined with computer image analysis technology, but there are certain differences between the two-dimensional root configuration obtained under the paper cultivation system and the three-dimensional root configuration of plants under natural conditions , cannot accurately represent the actual spatial distribution of plant roots in soil, so it is very necessary to quantitatively study the three-dimensional root architecture of plants

The main difficulty in the quantitative study of three-dimensional root architecture is that the concealment of the root system in the growth medium such as soil makes it difficult to observe the root architecture, and the complexity and overlap of the root system limit the measurement accuracy.

[0004] However, the above methods have disadvantages such as complex equipment, low reconstruction speed, and low reconstruction accuracy due to root occlusion and interlacing problems.
